Warren, who is in a heated campaign against U.S. Sen. Scott Brown, R-Mass., has been the subject of questions surrounding her heritage and what part, if any, in played in her hiring and career advancement at Harvard University.

Although the story has died down somewhat and a Rasmussen Poll showed it had not necessarily hurt her standing among voters in the Bay State, Republicans have been persistently pushing the issue.

In the video titled "Fraudster," the Mass. GOP highlights some of Warren's most notable gaffes in her responses to questions about the controversy as the situation unfolded.

For almost a decade in the 1980s and '90s, Warren listed her Native American ancestry in a directory of law professors compiled by the Association of American Law Schools, a move she said was to meet people "who are like I am," referring to the stories of Native American ancestry which were passed down by family members. When the directory proved fruitless as far as networking with other Native Americans, Warren said she stopped checking that box on the directory listing.

And as Harvard University, Warren's employer, was under fire for a lack of diversity hires in the 1990s, they touted the law professor as the school's first minority female hire, a situation Warren said she was unaware of until reading about the situation in the press.

Since these details emerged, a shaky series of events transpired which cast doubt on whether or not Warren was actually Native American.

Christopher Child of the New England Historic and Genealogy Society told the Associated Press that he found an 1894 document in which Warren's great-great-great grandmother is listed as Cherokee, which would make the Harvard Law School professor 1/32nd American Indian. However, the society later said that they couldn't validate the statement since they found an electronic transcript of the 1894 marriage license of her great-great-great grandmother O.C. Sarah Smith which listed her race as Cherokee but couldn't find a photo copy of the actual document.

Later, some news outlets began reporting that Warren's great-great-great grandfather Jonathan Crawford was actually a Tennessee militia member who rounded up Native Americans ahead of the infamous "Trail of Tears" march to Oklahoma. Those reports all quoted Cornell Law School professor William Jacobson, who was citing a genealogist.

Aside from the debate over whether or not Warren can be proven to have Native American ancestry, Republicans have insinuated that she used her heritage to boost her career, a claim that was denied by Warren and administrators from each of the universities she has worked at.

"Elizabeth has been straightforward and open about her heritage while the people who recruited her have made it clear it was because of her extraordinary skill as a teacher and a groundbreaking scholar," Alethea Harney, Warren's press secretary, said in a previous statement. "Scott Brown has been peddling nasty insinuations for weeks to distract from his million-dollar tax returns and multi-million dollar Wall Street fundraising. We’re getting back to the issues that really matter in this election, like how to level the playing field for middle class families."
